23 Claims.

This invention relates to forming machines and more particularly to forming machines operated by eccentric means mounted on one or more shafts, the eccentric means carrying one or more heads or other working parts which during operation of the machine partake of cyclic movement. The invention has to do particularly with adjustment of the relative angular positions of the eccentric means and the shaft or shafts on which the eccentric means are to be mounted. Such adjustment is accomplished by holding the eccentric means or certain thereof against rotation while turning the shaft or shafts. The invention further relates to other novel features and combinations of elements employed in a forming machine in connection with the adjusting mecha nism.

The invention is adaptable for use in forming machines such, for example, as that disclosed in my copending application Serial No. 497,792,.

new Patent t l-106,888. Such a forming machine may comprise upper and lower heads each partaking of orbital movement and which cooperate to perform operations on moving work. For example, the heads may carry dies which stamp or otherwise form work passing through the machine. Each head may, for example, be mounted on two parallel shafts rotating in the same direction. Thus the machine may comprise four parallel shafts, two in a horizontal plane and the other two in a second horizontal plane below the first two, each upper shaft being in the same vertical plane as one of the lower shafts. The two upper shafts rotate in one direction and the lower shafts rotate in the opposite direction. The four shafts carry eccentrics upon which the heads are mounted. Thus when the shafts are operating the respective heads move in orbits so that the dies or other working means carried thereby periodically cooperate to act on the work, at the same time moving laterally.

It is desirable in forming machines of the type above referred to to counterbalance the heads by counterweights. For example, there may be a counterweight for counterbalancing the upper head and a counterweight for counterbalancing the lower head such as disclosed in my copending application Serial No. 611,080. The counterweight for counterbalancing the upper head may be mounted on the same two shafts on which the upper head is mounted and the counterweight for counterbalancing the lower head may be mounted on the same two shafts on which the lower head is mounted. Each counterweight is mounted on eccentrics carried by the shaft. The eccentrics are so constructed and arranged that each counterweight exerts its force on the shafts carrying it at any given instant in a direction substantially opposite the direction in which the head carried by those shafts is exerting its force at the same instant. To bring about this result the high points, or points farthest removed from the shaft axes, of the eccentrics carrying the head should be disposed substantially in the opposite direction from the shaft axes relatively to the high points of the eccentrics carrying the corresponding counterweight.

To render a forming machine of the type referred to adaptable for various operations and for operating on work of various thicknesses and characteristics it is desirable that the eccentricity or throw of the eccentrics carrying the heads and counterweights be adjustable. In my said copending application Serial No. 611,080 there is disclosed mechanism for adjusting the eccentries so that when the throw of the eccentrics carrying the heads is adjusted the throw of the eccentrics carrying the counterweights will likewise be adjusted and the respective eccentrics will automatically maintain proper angular relationship about the shafts upon which they are mounted. Each head and each counterweight is mounted on an eccentric or eccentrics carried by each shaft supporting it with an eccentric sleeve disposed about each eccentric so that each resultant eccentric device acting on the head or counterweight as the case may be consists of the eccentric on the shaft and the eccentric sleeve thereabout, in other words, an eccentric and eccentric sleeve combination or resultant eccentric made up of an eccentric with an eccentric sleeve thereabout. The throw of the resultant eccentric is altered by relatively turning the eccentric sleeve and the shaft upon which it is mounted and which carries in non-rotative relationship the eccentric lying within the eccentric sleeve. In my said copending application Serial No. 611,080 I show means for insuring turning of the eccentric sleeves carryin the heads and the eccentric sleeves carrying the counterweights in controlled relationship so that the high points of the resultant eccentrics carrying the heads are between the eccentric sleeves and shafts and also I means whereby the eccentric sleeves and shafts may be fixedly positioned relatively to each other in adjusted angular positions, which means may be rendered temporarily inoperative to permit of angular adjustment between the sleeves and the shafts.

I provide, in a forming machine, a shaft, eccentric means on the shaft, the eccentric means and shaft being relatively turnable to adjusted positions but fixedly positionable relatively to each other in said adjusted positions, means mounted on the eccentric means to be operated thereby upon rotation of the shaft and means for holding the eccentric means against rotation while turning the shaft to adjust the relative angular positions of the eccentric means and shaft. I preferably rovide means engaging at least certain of the eccentric means and a head mounted on such eccentric means for holding the eccentric means temporarily against turning movement relatively to the head while the shaft is turned. Such means are preferably connected with the head and adapted to be temporarily disposed so as to engage the eccentric means to hold the same against turning movement relatively to the head. Desirably screw means may be employed which are connected with the head and which are adapted to be turned up against the eccentric means. The eccentric means may have a radial flange and the screw means may when turned up engage the flange of the eccentric means to hold the eccentric means temporarily against turning movement relatively to the head while the shaft is turned.

I further provide, in a forming machine, a shaft, eccentric means on the shaft, the eccentric means and shaft being relatively turnable to adjusted positions, means on the eccentric means and shaft engageable to fixedly position the eccentric means and shaft relatively to each other in said adjusted positions and disengageable to permit relative turning of the eccentric means and shaft, means mounted on the eccentric means to be operated thereby upon rotation of the shaft and means for holding the eccentric means against rotation while turning the shaft to adjust the relative angular positions of the eccentric means and shaft. The means on the eccentric means and shaft to fixedly position the eccentric means and shaft relatively to each other in adjusted positions are preferably engageable upon relative axial movement between the eccentric means and shaft in one direction and disengageable upon relative axial movement between the eccentric means and shaft in the opposite direction. The shaft preferably has means projecting generally parallel to its axis but offset therefrom adapted to interengage with portions of the cocentric means when the eccentric means is moved axially of the shaft and means are preferably provided for maintaining the eccentric means in interengagement with said projecting means on the shaft, said last mentioned means being operable to permit disengagement of the eccentric means and said projecting means on the shaft so that the eccentric means and shaft may turn relatively to each other. I preferably provide teeth on the eccentric means and shaft engageable upon relative axial movement between the eccentric means and shaft in one direction and disengageable upon relative axial movement between the eccentric means and shaft in the opposite direction.

I still further provide, in a forming machine, a shaft, a plurality of eccentric means on the shaft, the eccentric means and shaft being relatively turnable to adjusted positions but fixedly positionable relatively to each other in said adjusted positions, connections between the eccentric means effecting predetermined relative turning between one of the eccentric means and the shaft upon predetermined relative turning between another of the eccentric means and the shaft,

means mounted on the respective eccentric means to be operated thereby upon rotation of the shaft and means for holding one of the eccentric means against rotation while turning the shaft to adjust the relative angular positions of said eccentric means and the shaft.

1 further provide, in a forming machine, a shaft, eccentric means on the shaft, the eccentric means and shaft being relatively turnable to adjusted positions but fixedly positionable relatively to each other in said adjusted positions, means mounted on the eccentric means to be operated thereby upon rotation of the shaft, means for holding the eccentric means against rotation while turning the shaft to adjust the relative angular positions of the eccentric means and shaft and means including index means appliable to an end of the shaft for turning the shaft through a predetermined angle. The means for turning the shaft may comprise a sleeve appliable to an end of the shaft in non-rotative relation to the shaft, the sleeve having index means to facilitate turning of the shaft through a predetermined angle.

Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.

In the accompanying drawings I have shown a present preferred embodiment, of the invention in which Figure 1 is a vertical cross-sectional view through a forming machine, the section being taken transversely of the direction of feed of work through the machine;

Figure 2 is a vertical cross-sectional view taken on the line II--II of Figure 1;

Figure 3 is an enlarged fragmentary Vertical cross-sectional view of a portion of the structure shown in Figure 1 but with the retaining nut and sleeve removed and an indexed sleeve applied to the end of the shaft for turning it through a predetermined angle to relatively adjust the eccentric sleeves and the shaft, certain of the eccentric sleeves being shown as maintained against rotation relatively to the head;

Figure 4 is an end view of the structure shown in Figure 3 as viewed from the right hand end of Figure 3;

Figure 5 is a fragmentary elevational view showing the indexed sleeve applied to the shaft, and

Figure 6 is a fragmentary elevational view to enlarged scale of the indexed sleeve for turning the shaft,

Referring now more particularly to the drawings, there is shown a forming machine having an upper forming head 2, a lower forming head 3, an upper counterweight 4 and a lower counterweight 5. The upper head 2 and the upper counterweight i are mounted on two parallel upper shafts 6 and l. The lower head 3 and the lower counterweight 5 are mounted on two parallel lower shafts 3 and 9. All four of the shafts 6, I, 8 and 9 are parallel to one another, the shafts B and l lying in a horizontal plane and the shafts 8 and 9 lying in a lower horizontal plane. The shafts 6 and 8 lie in the same vertical plane and the shafts l and 9 lie in the same vertical plane.

The shafts t3 and l are rotated in one direction and the shafts 8 and 9 are rotated in the opposite direction. Referring to Figure 2, if,'for example, the shafts 5 and i rotate clockwise the shafts 3 and Q rotate counterclockwise. All'foul. shafts are rotated in unison at the same Speed by any suitable driving mechanism,;such,'ifor example as the driving mechanism'shown'in my said .copendin application SeriaLNo. .497,792. IDriving mechanismlfor the shafts is shown. at .the left hand sideoiFigure' lbutsince thedriving mechanism'forms no part of the present. invention'it will notbe described in detail. The outer orright hand ends of the shafts viewingFigure 1 are mountedin outboard bearings l0.

One of the shafts is shown 'fragmentarily to enlarged scale in Figure 3, although'in th'atfigure the .outboard'bearing [Ohas'been removedas have'the retaining nut and sleeve on the .end of the shaft and an indexed sleeve for turning the shaft has been applied. The shaft .comprises portions I! and lZfoi j'ournaling the shaft for rotation and,.intermediate those portions, eccentrio portions l3, I4 and 14a. The portion III is concentric with the shaft axis. The portion I2 is eccentric with respectto'thesha'ftaxis but is adapted to receive thereover an eccentricfsleeve 12a (Figure 1) keyed thereto. "When-theeccentrio sleeve [2a is appliedto the shaft portion [2 the outer cylindrical-surface ofthe sleeve In is concentric with the shaft axis. Therefore the shaft rotates in bearings cooperating with the portion ll of the shaft and the sleeve 12a keyed to the shaft.

.The eccentric shaft portions I 3 and. Ila form eccentrics for mounting one of the heads, asffor example, the upper head 2. The head straddles the .counterweight whichis .mounted about the eccentric shaft .portion .14. .In Figures 1 land .3 the high points of the eccentrics l3and -l4a.are disposed upwardly. The eccentricformounting the counterweight is .shownat l5, being keyed to the shaft and its high point extending downwardly or diametrically opposite thehigh points of the eccentrics l3 and Ma. 'Theeccentric'lS is applied to the shaft at the eccentric portion l4 thereof as shown inFigure 1,being.keyed thereto by a key [511.

The shaft has a radial flange I 6 against which lies a member I! which through projections is carried thereby and which.respectivelyenter recesses H] in the flange IE is held against turning movement relatively to theshaft. The member I? has a circumferential series of teeth '28 facing axially toward the right viewing Figures land 3.

An eccentric sleeve 2] having a .radial flange 2 la is mounted on the eccentric l3 and has teeth 22 normally in mesh with the teeth 20. The sleeve 2! in its normal position is disposed relatively to the eccentric [3 so that the high point of the sleeve is in the same plane containing and in the same direction from the shaft axis as the high point of the eccentric. vIn its end face the flange Zia has radial projections 23 which are radially aligned with each other and one of which passes through the high point of the eccentric sleeve. An annular member 24 is .disposedabout the shaft to the right of the sleeve 2! viewing Figures 1 and 3 and has in its lefthand face viewing such figures aligned radial slots 25 and in'its right hand face other aligned radial slots which extend at right angles to theslots 25. The bore of the annular member 24 is, as shown, much larger than the shaft so that the member 24 is free to move transversely of the shaft as well as angularly. The radial projections 23 enter andare guidingly receivedby the slots 25 so that thesleeve 2i and the annular member 24 may not rotate relatively to one :another but may partake only of'relativemovement longitudinally of the projections 23, this being permitted because thebore of the men'iberflislarger thadtheShelft.

Mounted over the eccentric l5 isan eccentric sleeve 31 having alignedradial projections ..3l|a at its left and right hand faces, all of which projections are in the same plane containing the shaft axis which extends at right anglestda. plane containing the shaft axis and passing through the high point of theeccentric sleeve 3!. In other words the projections am on the end faces of the eccentric sleeve 3| lie in aplane perpendicular to the plane of the paper viewing each of Figures 1 and 3.

The projections 3la at theleft hand face-of the eccentric sleeve 31 are vguidingl-y receive'd'by the slots 3|b in the right hand face of the annular member 24. Thus theannular member. 24 and the sleeve 3| may not relatively rotate but may partake of relativemovement longitudinally of the interfitting projections 35a and slots 31b. The sleeve Si is normally disposed withits high point in the same plane containing and in the same direction from the shaft axis as the hi h point of the eccentric l5. v

Mounted next the sleeve 3! is a member 34 similar to the member 24 and having aligned radial slots 3lc in its left hand face which extend at right angles to the plane of thepapers viewing each of Figures 1 and 3 andaligned radial slots 36 in its right hand face, theslots36 extending in the plane of the paper viewing each of Figures 1 and 3 and hence being disposed at right angles to the slots M0 in theleft hand face of the member 34. The member 34 like the member 24 has a bore larger than the shaft so that the member 34 may move transversely .of the shaft. The projections3 la at the right hand face of the eccentric sleeve 3! enter and areuguid- 'ingly received by the slots 310 in the left hand face of the annular member-34.

Mounted on the eccentric 14a is an eccentric sleeve 39 having a flange 33a having aligned radial portions 3%, the eccentric sleeve 39 being similar to the eccentric sleeve 2l. The projections 3% extend through the high point of the sleeve 39. The high point of the .sleeve'is normally in the sameplane containing and in the same direction from the shaft axis as the high point of the eccentric 14a. The projections 3% enter and are ,guidingly received by the slots 36 of the annular member 34. Thus the member 34 and the sleeve 39 may not relatively rotate but may move relatively to each other longitudinally of the projections 392). In its right hand face the eccentric sleeve 39 has teeth 40 adapted to mesh with teeth dfia on the eccentric sl eve [2a. A retaining nut 43b is threaded onto the shaft and bears against the right hand end of the sleeve I20. to hold the members assembled. a

When one of the'eccentric sleevestii and and the shaft are relatively turned the mecha nism just described results in correspondingly relatively turning the other of such sleevesand 'points of the resultant eccentrics or eccentric and eccentric sleeve combinations for the head and counterweight respectively directly opposite each other relativeto the shaft axis. This insuresthat the head and counterweight will-alwaysact .on

the shaft in opposite directions. When the sleeve lza is in place as shown inFigure, l and the nut 40b is turned up against the end of that sleeve all of the eccentric sleeves 2|, 3| and 39 are flxedly positioned relatively to each other and relatively to the shaft just as though the sleeves were integral parts of the shaft. This is because the member I? is non-rotatably mounted on the shaft, the teeth 20 on that member are in mesh with the teeth 22 on the sleeve 2|, the sleeves and the teeth 46 on the sleeve 39 are in mesh with the teeth 40a on the sleeve IZa, which sleeve |2a is keyed to the shaft.

When it is desired to relatively angularly adjust the shafts and the sleeves carried thereby the outboard bearings ll! are removed, the nuts 40b are removed from the ends of the shafts and the sleeves |2a are likewise removed. This leaves the eccentric sleeves 2|, 3| and 39 loose upon their respective eccentrics |3, i l and I ia and free to partake of suflicient movement axially of the shafts to disengage the tech 26 and 22. Of course when the sleeve |2a is removed the teeth 40 and 40a are disengaged. With all the teeth thus disengaged the sleeves 2 I, 3i and 39 are free to turn relatively to the shafts.

As above stated I providefor relatively angularly adjusting the eccentric sleeves and shafts by holding certain of the eccentric sleeves against rotation and turning the shafts therein. I hold the eccentric sleeves 2| and 39 against movement relatively to the head 2 by means of screws 4| which are mounted in threaded bores in the head and are adapted to be turned so as to thread inwardly or toward the shaft until their noses engage the flanges 21a and 39a of the sleeves 2| and 39, respectively. The screws ii have flat heads so that they create sufficient frictional resistance when turned up tightly against the sleeve flanges to hold the sleeves against turning. When the screws have been turned up to engage the sleeve flanges and the outboard bearing l9, nut dill) and sleeve |2a have been removed a special sleeve 42 is fitted over the end of the shaft. The sleeve 42 is keyed to the shaft so as to be non-rotatable with respect thereto. It is externally knurled so as to be adapted to be gripped and turned by a Wrench. The sleeve G2 has index means 43 thereon to facilitate turning of the shaft through a predetermined angle. The index means on the sleeve 42 may cooperate with an index mark 34 on the sleeve 39.

When the shaft is turned by the use of the sleeve 42 it will rotate relatively to the sleeves 2| and 39 which by the screws are fixedly held relatively to the head 2 so that they cannot turn. The connections above described between the eccentric sleeves 2|, 3| and 39 insure predetermined relative turning between the eccentric sleeve 3| and the shaft upon predetermined relatiVe turning between the eccentric sleeves 2| and 39 and the shaft. As explained above, such connections insure that planes through the shaft axis and through the high points of the eccentric sleeves 2|, 3| and 39 are maintained parallel which in turn results in the force of the counterweight always being exerted at a point diametrically opposite the point on the shaft at which the force of the head is exerted.

When the shaft has been turned to the desired extent the sleeve 42 is removed, the screws 4| are threaded back clear of the sleeve flanges and the sleeve l2a, the nut 40b and the outboard bearing ID are replaced. The sleeves are then held in fixedposition relatively to each other and to the shaft and the machine is again ready for operation.

Since the shafts are all geared together for operation in unison it is only necessary that one of the four shafts be turned in the manner above described toeffect adjustment of all. Turning of one shaft results through the connecting gearing in turning of all four shafts. However it is necessary to turn up the screws 4| to hold all eight of the eccentric sleeves for mounting the heads against turning and to remove or at least loosen all of the holding nuts and sleeves. The holding sleeves corresponding to the sleeve |2a must be capable of movement toward the ends of the shafts far enough to permit complete disengagement of both sets of teeth corresponding to the teeth 20 and 22 and the teeth it and 40a. After the adjustment has been effected all of the screws 4| should be turned back to clear the flanges of the eccentric sleeves and the holding sleeves and nuts should be applied to all four shafts. The outboard bearings should of course also be applied to all four shafts before the machine is again put in operation.
